3 Years Without Problems
These spark plugs are 3 years old with over 30K and my vehicle starts as fast as the day I put them in. It takes more then 2 hours to replace the plugs on my Mercury Cougar, so I want to do it only when necessary.

Good And Reliable
I run Iridium XP104 in my '02 Ranger and also their XP5224 version in our 3.7L V6 Jeep KJ Liberty with very good results. Neither one is a real joy to change plugs in, especially the vette - brutal - so you want to know the plugs you put in will work and LAST a long, long time. Like the other reviewer said, no miracles but they're top quality and reliable. For $6 for the best versus $2 for possible junk, you're crazy to put cheap plugs in any vehicle.
